A rush of anticipated public offerings from tech unicorns like Uber and Airbnb could have a major impact on one of the country’s priciest cities.

Real-estate agent Jeffrey Hyland and his team recently trawled Forbes’s wealth ranking and sifted through tech databases to identify the 50 people most likely to strike it megarich from the anticipated public offerings of tech unicorns like Uber, Palantir, Pinterest, Slack, Airbnb and Postmates.

The group then sent each of those 50 people an embossed box jammed full of glossy marketing materials for the property they are peddling: a $110 million parcel of land in Tiburon, just north of San Francisco.
